What happened
Global positioning system data indicated that the airplane had taken off about 41 minutes before the accident and had flown about 60 nautical miles. The last portion of the data indicated that the airplane was making a descending left turn toward the departure airport. The last recorded position was almost directly above the accident site; the airplane impacted a field in a near vertical attitude about 1.2 miles from the airport. Based on the last two recorded data positions, the airplane was in a 60 foot-per-minute rate of descent at 115 knots on a heading of 351 degrees. This data indicated that the airplane was well above the airplane’s stall speed and provided no explanation for the mishap. Postaccident examination of the airplane and its engine did not reveal any anomalies that would have precluded normal operation.
